| Capacity | Good for |
|---|---|
| 2–3.5 L | Solo / couple |
| 4–6 L | Family of 3–4 |
| 7 L and up | Large family / batch cooking |
Running cost
Most draw 1,200–1,800W but run briefly. Say 1,500W for 15 min = 0.375 units ≈ 1.5–2 THB per use — cheap and faster than preheating an oven.
Features to check
- Controls: dial (cheap, durable) vs digital/touch (programmable, precise)
- Basket/tray: easy to remove and non-stick
- Safety: auto power-off when the basket is pulled out
- Footprint: check your counter space first

Pros: little oil, fast, easy to clean · Cons: limited capacity per batch; some foods aren't quite like deep-frying.
Verdict
Pick the right capacity for your household first, then consider controls and cleaning. Running cost is a non-issue — just a few baht per use. If you're upgrading your kitchen at the same time, see our best rice cookers guide 2026.
